Application filed April 29, 1911. Serial No. 624,154.

To all whom it, may concern:

Be it known that I, Join KLATT, a citizen of the United. States,residing at Blue Earth, in the county of Faribault and State ofMinnesota, have invented a new and use ful Yieldable lVheel; and I dohereby declare the following to be a "full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a new and useful resilient vehicle wheel, moreespecially adapted for use upon automobiles.

The invention in its broadest scope, aims as its primary object, toprovide a simple,

ellicient, novel and practical wheel of this design, to be used in placeof automobile wheels having pneumatic tires.

A further object of the invention is to provide an inner and outer rim,having resilient members or springs arranged between them, saidresilient members or springs having oppositely arranged lips to engageopposite sides of the inner rim, to preventlateral movement of themembers or springs.

A vfurther object of the invention is to provide guide loops archingover the inner rim, for guiding the outer rim as it yields relativelywith regard to the inner rim. The inner rim is provided with recesses toreceive the sides of the loop for holding them in place.

A further object of the'invention is the provision of a solid tire tosurround the outer rim, in place of the pneumatic tires now in use.

In the drawings, there is only disclosed one embodiment of theinvention, but in practical fields this embodiment mayrequn-e'alterations, to which the applicant is entitled, provided thealterations are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings, and claimed.

In the drawings: Figure 1 is a view in elevation of a portion of avehicle wheel, constructed in. accordance with the invention. Fig. 2 isan enlarged detail sectional View on line 2-2 of Fig. 1. Fig. 3 is adetail View of one of the spring or resilient members.

Reierrin more particularly to the drawings, 1 designates the usual formof hub,

while 2 designates the spokes of the wheel, which connect with the innerrim .3. Surrounding the inner rim is an outer rim 4, about whichsurrounds a solid rolled rubber tire 5.

Arranged between the inner and outer rims are a plurality of leafsprings 6, of the shape shown in the drawings. These springs are securedin place by means of the bolts 7 (which are threaded into the inner rim)and the lips 8, which engage upon each side of the inner rim. The objectin providing the lips 8 is to provide means to prevent the leaf springsfrom oscillating laterally, incident to the movement of the outer rimwith regard to the inner rim. To further insure against this lateralm0vemont, the free ends of the springs engage slight depressions 9 ofthe inner circumference of the outer rim.

To guide the outer rim with relation to the inner rim, incident to itsunivement with regard to the inner rim, U-shaped metallic loops areprovided. These loops 10 arch over the inner rim, and are secured at 11to the outer rim, as shown. To hold the loops, in place with relation tothe inner rim,- the inner rim is provided with a series of recesses 12,the end walls of which designated by the character engage on each sideof the side portions of the loops. These end walls are shaped in suchwise as to permit. the loops to freely move relatively with regard tothe inner rim, as will be clearly understood. The inner rim is providedwith recesses 12 adjoining the recesses 12, designed for the purpose ofreceiving the ,lips 8.

From the foregoing, it is to be noted that there has been devised anovel, etlicient and simple and practical resilient vehicle wheel, andone which has been found to be an err cellent substitute for automobilewheels having pneumatic tires.

The invention having been tort-h, what is claimed as new and useful, is:

1. in combination, an inner and outer rim having resilient leaf springsarranged therebetween, metallic loops arching over the inner rim andconnected to the outer rim, the inner rim having a plurality ofrecesses, to receive the opposite sides of the loops, for holding theinner rim in place, as it vibrates vertically, means for connecting thesprings to the inner rim, said springs having lips integral therewith,engageable upon either side of the inner rim to prevent oscillatingmovement of the springs.

2. In combination, an inner and outer rim having resilient leaf springsarranged therehetween, metallic loops arching over the inner rim andconnected to the outer rim, the inner rim having a plurality ofrecesses, :0 rec .ive the opposite sides of the loops, for holding theinner rim in place, as it vibrates, means for connecting the springs tothe inner rim, said springs having lips integral herewith, engageableupon either side of the inner rim to prevent oscillating move ment ofthe springs, said outer rim having slight depressions to receive thefree ends of the springs to further insure the springs againstoscillating lateral movements.

3. In combination, an inner and out r rim having resilient leaf springsarranged there between, the outer rim having lugs, metallic U-shapedloops arching over the inner rim and pivoted between the lugs, the innerrim having a plurality of recesses to receive the -opposite sides of theloop for guiding the rim having slight depressions to receive the freeends of the springs to further insure the springs against oscillatingmovements.

In testimony whereof I have signed my name to this specification in thepresence of two subscriblng WltlIlQSSt-ZS.

JOHN KLATT.
